    It is within the realm of possibility that their work may usher in a change in global economics as profound as the Industrial Revolution. As may be expected, press reports dealing with asteroid mining have been numerous, ranging in scope from short and breezy to broad and serious, and in quality from accurate to impressionistic to simply uninformed.

    And once you found life, what if you could accelerate time and watch it evolve? What might you find? These are not the questions Jon Gruber ponders as he pedals to his next carpentry job. Over thirty and unmarried, he doesn't even own a car. But a new assignment challenges him to rethink his place in the world. Is he a loser? Or is he about to become a partner in an experiment of phenomenal discovery? Webster Adams, astronomer, inventor, and Jon's latest client, performs such an experiment. To Webster's amazement, he finds planets and cultures beyond his wildest dreams. His little universe turns into a discovery machine--an overnight goldmine. He and his crew observe societies so far past them on levels of technology and spirituality, that the world will be forever changed. Webster's lovely daughter, Whitney, also overwhelms Jon. She opens his eyes to the deeper meanings within the experiment by finding the most advanced beings within the project--the spirit guides from Theta 7. The Little Universe is a mind expanding concept. For Webster Adams, one question immediately comes to light. "If I can create a universe," he wonders, "then who created ours?" Can it be proven that some form of God exists? Or is life random and free-flowing without purpose? Along with Jon, you, the reader, will be presented a new perspective on life and your role in the great mystery of the universe.
